Application of CE QUAL-W2 Model: An Approach to the Thermal Structure in the Miguel Martínez Isaza reservoir, Concordia, Antioquia, Colombia
Journal Title: TecnoLógicas - Year 2019, Vol 22, Issue 46
Abstract
Hydrodynamic modelling of temperature is a tool that contributes to the management of reservoirs because it is possible to create scenarios with different conditions to predict the behavior facing the meteorological changes and the mixing processes. This work seeks to contribute elements of analysis to the functioning and identification of the external factors that dominate the thermal dynamics of a tropical reservoir of mountain. The temperature and the water level were registered in three places of the reservoir, during three campaigns of sampling. In addition, we measured the inflows and outflows to the reservoir and analyzed the climatic historical records. With this information the two-dimensional model CE QUAL-W2 archives was build, in order to simulate 3 climatic periods (dry, transition and wet) and one where El Niño is included. It is clearly demonstrated that Santa Mónica creek has a greater influence in the water extraction. The external factors like the increase of the water extraction and the climatic scenarios influence the temperature and availability of the reservoir, being El Niño scenario the most critical, where the reservoir approximately increases its temperature 3°C and the level of the water diminishes a meter. The reservoir is increasingly susceptible to the shortage of supplies and the decrease of quality in the scenes of drought with the increase of the resource demand. The model is a useful management tool of the reservoir for the future scenarios of climate change.
